In high spirits, having got full pay organised (7)
I believe the answer is:
playful
'in high spirits' is the definition.
(in high spirits can mean playful or cheerful)
'full pay organised' is the wordplay.
'organised' is an anagram indicator.
'full'+'pay'='fullpay'
'fullpay' anagrammed gives 'PLAYFUL'.
'having got' is the link.
(Other definitions for playful that I've seen before include "Frolicsome" , "Frisky" , "Fond of games; light-hearted" , "In high spirits" , "Teasing, unserious" .)
